Smc Pneumatics KCH06-00 Union Straight Tube Fitting

Product Description

The SMC PNEUMATICS KCH06-00 is a straight union push-to-connect tube fitting designed for quick, tool-free connections in pneumatic and fluid transfer lines. Constructed with a brass body and polybutylene components, it accepts 6mm outside diameter tubing and is rated to a maximum working pressure of 145 psi. This fitting is used to join two tube segments in a straight, inline configuration without threading or crimping. Licensed plumbers, pipefitters, and pneumatic system technicians install this type of fitting in compressed air, water, and compatible fluid distribution systems.

This fitting is suited for residential and light commercial pneumatic plumbing and fluid system installations where fast, reliable tube connections are required. Its push-to-connect design reduces installation time and allows for straightforward field repairs or line modifications. The KCH06-00 is appropriate for applications where 6mm OD tubing is routed in straight runs requiring a secure union joint. It complies with RoHS requirements, making it suitable for installations with restricted hazardous substance requirements.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or qualified pneumatic system technicians. Before servicing any line, depressurize the system fully and verify the line is free of fluid. Ensure tubing is cut cleanly and squarely before inserting into the fitting to achieve a proper seal. Follow applicable local codes and system manufacturer guidelines for pressure rating verification before returning the system to service.
